Title:
銀アセチリド及びその製造方法
Document Type and Number:
Japanese Patent JP6815918
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide silver acetylide which is capable of producing a porous carbon material comprised of a dendritic carbon nano structure of a large specific surface area and a large mesopore volume (especially mesopore volume of mesopores having a pore diameter of 2 to 5 nm) and is useful in producing a carrier carbon material for preparing a catalyst for use in a solid polymer type fuel cell excellent in durability and power generation characteristics (especially output voltage characteristics at a low current density), and a method of producing the same.SOLUTION: The silver acetylide is of a MCtype derived from acetylene by substituting hydrogen atoms thereof with monovalent silver atoms, is of a three dimensional dendritic structure, and has a silver-carbon molar ratio, i.e., (M/M) in a range of 1.0≤M/M≤1.06, provided that (M) represents the molar amount of silver calculated from the residual amount at about 400°C in a thermogravimetric analysis under an air atmosphere up to 400°C using a decomposition product resulting from an autolytic explosion reaction as a measurement sample, and (M) represents the molar amount of carbon which is the molar amount thereof other than the molar amount of silver. The method of producing silver acetylide as described above is provided.SELECTED DRAWING: None
